2. Claims.

My invention relates to a water system for paper wrapping machines and I declare the following to be a full, clear concise and exact description thereof sufiicient to enable anyone skilled in the art to which it appei'tains to make 'issued Aug. 16, 1938, No. 2,127,028 and issued Dec. 3, 1935, No. 2,022,911.

Heretofore in paper wrapping machines the water used to moisten th paper to prevent it from buckling especially in hot weather, as it is fed into the machine was applied to the side of the paper that came next to the bread. This has been found harmful for the'reason that it allows the water to come in contact with the bread and thereby causes a mold to form thereon after a very short interval. This mould renders the bread unfit for use.

The present invention avoids this harmful effeet above mentioned by applying the water or moisture to the outside of the wrapper or to the side that does not come into contact with the bread. l g

The invention contemplates water'cups located above the paper which allow drops of water to fall down upon asponge that makes contactwith certain pressure rollers employed to feed the paper into the machine.

Th invention will be understood by referring to the drawings in whichlike characters refer to like parts throughoutthe specification.

Fig. 1 shows a perspective view of that portion of a paper wrapping machine that pertains to the present invention, parts being in section and parts broken away.

Fig. 2- is' a detail enlarged view, showinga centralvertioalisection, parts being in full, ofa water cup and immediate parts that are employed in the machine.

Fig.5 isadetailwiew showing aperspective of a sponge employed. 7

Fig. 6 is a detail view'somewhat' nlarged,showing a gear and ratchet, employed in the driving mechanism, parts being broken away.

Referring more particularly to the drawings only such parts of the bread wrapping machine are shown as pertain to the present invention. The machine embodies a frame I having horizontal bars 2, 2. Upstanding brackets 3, 3 are bolted, at 4 or'otherwise' secured to the upper surfaces of bars 2, 2 opposite to each other. Each of th brackets has mounted to its top part'a horizontally projecting shelf 5- bolted at 6' thereto. A trough 1' is secured to-the under side of said horizontal shelves 5; 5*by welding or in any other suitable manner.

' Five spaced transverse recesses or apertures H) aremade in the curved base H of trough 1 into which-is fitted correspondingly shaped projecting parts 12 of sponge l3; Sponge l3 rests in trough l and its projecting-parts l2 bear against -the upper parts of th outer surfaces of five spaced"cooperating'pressure rollers 15 preferably madeof rubber. Pressure rollers 15 are mounted to turnwith rotatable shaft 16- which has bearings at either end in vertically sliding or floating bearing blocks l1, 11.

Each of the bearing blocks IT, I! has onits opposite'lateral sides ribs formed integral there'- with that slide in corresponding grooves 18 made in the upstanding inner sides of brackets 3, 3.

The means for elevating bearing blocks H; H', whereby to relieve the pressure of rollers 15 against paper 20' and roller 2| therebeneath', hereinafter mentioned, contemplates a crank shaft 25 having bearings in elongated open recesses 26 made in the upstanding ends 121, 21 of the narrow plate 28. An elbow or handle 29 is formed at on end of shaft 25, whereby to aid in turning said shaft at will. Shaft 25 is oifset at 2-1 to clear water cups 3!! hereinafter described. I

Narrow plate 28 is bolted to brackets 3; 3 by the same bolts 6, 6 that holdshelves 5, 5 in place on top of brackets 3, 3. Plate 28 is mounted onshe'lves 5, 5 a little off center thereof, whereby to aid also in clearing cups 30 from the offset portion 21 of shaft 25.

Journals 35', 35ers mounted above horizontal shelves 5, 5 to turn idly on shaft 25. A connecting rod 36 is screw mounted at its lower end to each of the vertically movable bearing blocks IT, I! and at its upper end to a threaded aperture in the-under surfac of each of the iourna'ls 35,

A coiled spring "is disposed about each-"of which is adapted to-iiiake contact with the upper horizontal an surface of elevation 43 formed in tegral with the upper surface of shelf 5. Like which slide in complementary grooves in the contiguous sides of guide 10... Guide is bolted at 12 or otherwise secured to member 13 which is V bolted or welded to frame beam 60 at 14.

' The lower part of rack 69 has an elongated slot at 15. An adjustable member 16 has a hori-' zontal part that engages said part at the slot 15.

' A connecting rod 18 is pivoted at 19 to member wise collars 45, 45 are mounted on shaft andturn therewith. They are located adjacent and on the opposite sides of journal's 35, 35, and aid in holding journa1s'35, in place.

Fig. 1 shows pressure rollers I5 in elevated position, whereby to relieve the pressure on paper 20 and roller 2| therebeneath. In order to lower said rollers I5 onto paper 20 and roller 2!, crank .handle 29 will be turned at right angles as shown in said' Fig. l. In this position the fiat surfaces 42 of rollers 4 I will rest upon the contiguous surfaces of elevations 43. In this position also coiled springs. 40 will force bearingjblocks I1, I1 downward to lowermost position thereof, and,

therefore, rollers I5 downonto paper 20 and roller 2|, therebeneath. j

Rollers I5 hereinab'ove mentioned are mounted to turn with shaft I6 which has bearings in blocks I1, I1, as above stated, whereas roller 2| there beneath is mounted to turnwith shaft 5| having bearings in the lower integral portions of brackets 3, 3.; All of the rollers I5 and the roller 2| cooperate to move the paper 20there'between into the paper wrapping position within the machine, which movementis transverse to the feed of the bread, not shown.

The means for rotating said rollers I5 and 2! intermittently in opposite dirertions, whereby to feed thepaper 20 contemplates spur gear 53 fixed to turn with the outer extended end of shaft I6. Spurjgear 53 meshes with another spur gear 54 therebeneath fixed to turn with the extended part 55 of shaft 5|. Shaft I 6 has a further extene sion beyond the location of spur gear 53 to which is mounted to turn therewith a bevel gear 56 in mesh with another bevel gear 51 located on the same plane and fixed to turn with shaft 58 disposed at right angles to shaft I6 and having bear-- f ings in upstanding bearing brackets 59, 59.

' The lower ends of said brackets 59, 59 are bolted I r or otherwise fastened to frame beam 60. Shaft 58 is held in place by boss 6| at one end and by hub 62 pinned at 63 to shaft 58 of beveled gear 56 at the other end. An elongated gear 65' is mounted on shaft 58 intermediate its bearings 59, 59. A pawl 66 fastened to the end of gear 95 and ratchet 61 fixed to turn with shaft'58 will cause an intermittent rotation of shaft 58. Shaft .58 forms the driving member through the gears and a beveled gears'aforementioned for feeding the'paper 20 into the machine. Its loose mounting on. shaft 58 with the aid of the ratchet 61 will cause the paper 20 to be fed into the machine 7 when gear rack 69, hereinafter mentioned, moves downward but will not cause the paper 20 to be fed when said rack-09 moves upwardly. This intermittent rotation of shaft 58 will give sufficient.

7 ed to have a sliding fit in angularly positioned guide 10. Tothis end it has lateral ribs II, 1|

16. The opposite end of connecting rod 18 is pivoted to crank pin 19 of the adjustable block 80.

mounted to slide in guide member 81 fastened to one of the spokes 82 of wheel 83, as shown in patent to Hayssen, issued Aug. 16, 1938, No. 2,127,028.

Wheel 83 is mounted to turn with power shaft 84 having bearings in frame I. The rotation of wheel 83 will cause connecting rod 18 to reciprocate, whereby to exert an upward push and downward pull on rack 69. This in turn will cause the rotation of gear 65 on the downward pull to rotate rollers I5 and roller 2| by means of the intermediatebevel gears 56, 55an'd spur gears 53 and 54 as hereinbefore explained. This rotation of rollers I5 and2l, which is intermittent'will feed paper 20 into the machine for wrapping the bread.

The above mentioned wheel 83 andits immediate parts for actuatingrollers I5 and roller 2! in an intermittent manner are descri'bed in patent to Hayssen, issued Aug. 16, 1938, No. 2,127,- 028, to which reference may be had for more par ticuler description. 1

A roll of paper 90 used as aninside wrapper for the bread, not shown, is mounted on shaft 9| resting at either end in open bearings 92, 92 bolted at 93 to frame I.- Paper 90is fed up under paper 20 as clearly shown in Fig. 1.

The novel means for applying moisture to the outside surface of paper 20, whereby it will serve its purpose without coming in contact with the bread embodies said cups 30, five of which are shown although any number may be used to conform with the width of paper used. Each of the cups 30 has a flanged top closing member |0| and similar bottom closing member I 02. A cyline drical glass casing I03 is mounted-therebetween. Cork gaskets I04, I04 resting in saidtop and bottom members ml and I02 respectively aid in sealing the container against leakage.

An elevated part I05 is formed on top member IOI. It has a threaded throat part I06 for engaging the upper threaded part of hollow centrally disposed tube I01. .A rotatable cover I 08 is mounted to turn on elevated part I05. Its peripheral edge is knurled to aid in turning the same. Cover I08 has an aperture at I I0 adapted to register with aperture. III made in the horizontal upper surface of top member IOI when said cover I08 is turned to a predetermined position. A washer II 2 is mounted on cover I08 about tube I01. Above washer H2 is a ring 5 which has an extension forming an upstanding flexible spring H6. The free end of spring I I 6 rests against the outer knurled surface of adjustable collarl I1 to aid in holding it in place.

A look nut H8 is threaded to the external threads of tube I 01 above ring I I5 to hold the parts below in place. Collar 1 has internal threads for screw mounting it to the upper end of tube I 01. It has also a central aperture at I20 for the upward projection of the upper portion |2| of needle valve 123. The lower end of tube I 01 is externally threaded to a nozzle I25 having a valve seat at I26 and tapering open passageway at I21. The outersurface of nozzle I25 is threaded for engaging and holding in place the bottom closing member I02.

A thimble or cylindrical member I30 is also screw mounted to the external threads of nozzle I25. The lower outer surface of cylinder I30 has external threads at |3| for engaging correspondingly threaded apertures made in narrow plate 28, whereby to hold said cups 30 in upright assembled position. A fiat sided part I32 is formed externally on each of the cylinders I30 to aid in turning the same into its threaded apertures in plate 28. A narrow cylindrical passageway I35 is made in the central lower portion I36 of cylinder I30 for the passage of the water. The upper endof the passageway is funnel shaped at I31. An angular lead nozzle I38 is attached to the external threads I3I, whereby to direct the water towards the central portion of the sponge I3.

The upper part I40 of thimble I30 has openings |4I |4| opposite each other which are closed by a glass cylinder I42 fitted within the interior of said cylinder I30.

The larger diameter I45 of needle valve I23 fits loosely within the tube I01. A shoulder I46 is formed on said needle valve I23 by reducing the upper portion in diameter. The lower end of a coiled spring I41 rests on said shoulder I45. Its upper end rests against the lower inner surface of adjustable collar II1, whereby said spring I 41 will exert a pressure downward on needle valve I23 to hold it to its seat I26 or to adjusted position relative thereto.

The means for elevating needle valve I23 against the tension of spring I 41 contemplates a forked lever I50 having a handle to which the upper reduced angled part |2I is pivoted at I53. The free ends of lever I50 rest against the upper surface of adjustable collar I I1 when acting as a lever. By tipping said lever I50 up into dotted line position illustrated in Fig. 4, needle valve I23 will be unseated. It can be adjusted to govern the amount of flow of water through passageway I35 by turning collar M1 to the right or left. Spring II6 will hold it in adjusted position. An aperture I55 is made in the side of tube I01 adjacent its lower end, whereby to admit water from cup 30 therein.

In operation the user of the machine will first fill cups 30 with water. This can be done by turning covers I08 to bring apertures M0 to register with apertures III in member IOI. Needle valve I23 can be adjusted to govern the amount of water flowing from cups 30 by turning collar 1 to a predetermined position. They will be lowered then towards their seats I20, by actuating levers I to full line position illustrated in Figs. 2 and 4.

Rollers I5 will be lowered against paper 20, paper 90 therebeneath and roller 2| under both by turning crank handle 29 in the are shown by dotted lines shown in Fig. 1.

The motor power, not shown, will turn wheel,

83 to actuate gear rack 66, whereby to turn gear and shaft 51 intermittently. Shaft 51 in turn will rotate rollers I5 and roller 2| through the medium of bevel gears 51, 56 and spur gears 53 and 54 as above explained.

The water from cups 30 will drip on to sponge I3 which will dampen the outer surfaces of roller I5 that come into contact with the outer surface of paper 20. The paper thus dampened on its outer side will move into the machine without crimping or buckling and without dampening the bread, not shown.

Rolls of paper 20 and can be replaced easily from time to time by setting new rolls into their respective bearings. Likewise the free ends of paper 20 and 90 can be fed easily in between rollers I 5 and 2| when found necessary.
